Keywords: NTU, suspended-sediment concentration, turbidity, turbidity sensor
Turbidity sensors are frequently used for real-time measurement of solids concentration in water. Non-soil objects present in a water sample, including algae, organic matter, various microorganisms, colloidal material, and dissolved molecules such as tannins and lignins, may affect the turbidity readings. This paper reviews various technologies for sediment concentration measurement, presents the experimental results of a simple and inexpensive turbidity sensor developed in this study for measuring sediment concentration, and discusses potential approaches to improve the sensor.(Download PDF) (Export to EndNotes)
